Abstract: 1,032,402. Brush-making machines. LA BROSSE AND J. DUPONT REUNIS. Aug. 4, 1964 [Aug. 2, 1963], No. 30865/64. Heading A4K. A multiple tufting head is provided for . inserting a whole row of bristle tufts, in a bored brush stock, in a single operating stroke and the operative cycle of the machine also includes the simultaneous formation of the tuft anchors, for the row, by a punching out operation performed on a metal strip. As shown, a bored brush stock m is mounted on a conveyer 8 beneath the multiple tufting head. Bristle supply arrangements: the bristles 45 are fed, through curved magazine 44, towards a picker bar 2, by a head 42c under the pressure of a weighted lever 42a pivoted at 40. The picker bar 2 has a number of notches 3 equal to the number of bristle tufts in a row and these are over-filled by a vibrating motion and the surplus removed, on withdrawing the bar 2, by fixed bars 46. The charged picker bar 2 is moved by bell-crank lever 41, operated by cam 34, into the head 4 (Fig. 10) where it strikes a latch (Fig. 26, not shown). The latter releases bars 89 and 90 so that these fall, under spring action, and bars 89 extract the bristle bundles il-12 from notches 3 of bar 2 and locate them in throats hl-12 of channels j1-12 The bristle supply is maintained, during replenishment of magazine 44, by the operation of fork 117 by means of pneumatic rams 122 and 124. Tuft forming and setting operations: as the empty bar 2 is withdrawn from head 4, the metal strip f is fed, from reel 47 to place a new length opposite punches 1. The tufter head has an internal sliding core 80, 81, 78a, 78b, 79a and 79b. Parts 78a, b and 79a, b also slide relatively to parts 80, 81 and are driven by the direct connection of rod 83 with pin 82. The rod 83 is operated by cam 86 to impart downward movement to the core and thus initially to close gap 78a and bring the ends of channel 5 into engagement with throats kl-12, thus providing a continuous guide path for the anchors formed from strip f. The anchors are simultaneously formed by punches 1 propelled by lever 74 to punch out alternate segments of strip f and allow these to be removed from waste channel 206 by suction and rotary brush 107. On the continued downward travel of rod 83, the head 4 moves into contact with the brush stock and, at the same time, tongues 6 are driven by crank 69 to propel the anchors (which are left in the gaps between the punches 1) into the bights of bundles i1-12 and carry them into the brush stock. On completing the downward stroke of head 4, the co-action of abutments 91 and 102 raises the bars 89 and 90 to their upper latched position. The multiple heads are constructed in longitudinally split form to facilitate machining of channels jl-12. The delivery ends of the channels may lie on a curve to provide a curved row of tufts. The machine is mounted on an adjustable base.

Title: Improvements in contact for connection with a glass substrate carrying electrical conductors
IPC: H01R12/72
Filed: 1964-08-04
Abstract: 1,040,998. Two-part couplings. ELCO CORPORATION. Aug. 4, 1964 [Aug. 8, 1963], No. 31077/64. Heading H2E. A double-ended contact which is suitable for interconnecting a glass board 42 having printed circuitry 44 thereon, and contacts 50 mounted on a conventional printed circuit board, has one end bifurcated by a narrow slot 26, and the other end formed with a pair of widely spaced parallel fingers 30, defining between them a gap for receiving the glass board, the parallel fingers 30 each being provided with at least one inwardly projecting bump 38 to make contact with the printed circuitry. The end 14 of the contact may engage a contact 50 on the printed circuit board, having an identical contact making portion, this contact extending through the board 48 to project as terminal 52 to which wire wrap electrical connections may be made. The end 12 of the contact may engage circuitry on both sides of the glass board, or if a board has circuitry only on one side, two boards may be mounted back-to-back. The two ends may be disposed at an acute angle with respect to each other, as shown in Fig. 2, or in a further embodiment, Fig. 5 (not shown), the axes of two ends are in the same plane but arranged so that the narrow slot and gap for receiving the glass board are perpendicular to each other. In a final embodiment, Fig. 6 (not shown), the planes of the two ends are parallel but displaced from each other, so that the contacts may be arranged alternately so that the end of one contact 14 lies above the axis of end 12 and the end of an adjacent contact lies below the axis of end 12, thus allowing contact to be made to two rows of contacts secured to the printed circuit board. The bumps 38 on the contacts may be soldered to the conductors on the glass substrate for permanent connection in any of the embodiments.

Title: Improvements in or relating to electrical control devices

IPC: B60L15/04

Abstract: 1,207,302. Control of D.C. motors; charging and discharging batteries. SCOTTISH AVIATION Ltd. 11 Oct., 1967 [11 July, 1966], No. 31124/66. Headings H2H and H2J. In a battery-vehicle, the number of cells in a group to be placed in circuit with a motor is selected to provide a desired voltage, the position in the battery of the selected group of cells being changed cyclically. Initially, a master switch MS is closed, and an accelerator pedal is depressed to close a starting switch SS and complete a connection to the movable member of an acceleration switch ACS. Battery unit BU1 energizes contactor BCMC1, and a circuit is completed through datum switch DMS to a datum contactor DC1. The traction motor MA is thus supplied from the battery unit BU1. Further depression of the accelerator causes the movable member of the switch ACS to move from one contact to another, while the movable members of the deceleration switch DCS, datum switch DMS, and auxiliary switches XS1, XS2 remain stationary. When the switch ACS is moved to its fourth position, for example, contactors BCMC2-BCMC4 are closed, the confactors BCMC1-BCMC3 being maintained by holding contacts BCHC1-BCHC3. If the accelerator pedal is released, the movable member of the acceleration switch ACS remains on contact 4, but the datum switch DMS rests on contact 1, and the gap in the movable member of the deceleration switch DCS is opposite its contact 1. The movable members of the auxiliary switches XS1, XS2, are also moved around by three contacts. Battery contactors BCMC1-BCMC3 become de-energized so that battery units BU1-BU3 are out of circuit, only the unit BU4 remaining in circuit. Similarly, the datum contactors DC1-DC3 are de-energized. When the accelerator pedal is depressed again, the movable member of the acceleration switch ACS continues its movement, but contact 4 becomes, in effect, the first contact and unit BU4 becomes the new datum in the battery. Thus, release of the accelerator pedal leaves the acceleration switch in its last position and causes the datum and deceleration switches to disconnect the appropriate number of battery units previously in circuit and to establish a new datum unit for the acceleration switch. When the final battery unit BU8 is reached by depression of the accelerator pedal to its fullest extent, switch FVS closes to energize relay FVR and operate contactor FVC. This brakes the ring of battery units so that the complete battery is not short-circuited. The auxiliary switches XS1, XS2 move with the switches DCS and SMS so that the horn and lamps are always connected to a battery unit in circuit. The insertion of a charging socket into plug CP opens an interlock switch D1S so that operation of the accelerator pedal is ineffective during the charging operation.

Abstract: 520,709. Television. JONES, W., and PYE, Ltd. Oct. 28, 1938, No. 31289. [Class 40 (iii)] The rectified signals are applied to the grid of an amplifying valve V1 and the synchronizing signals appear at the output of the valve. The output circuit is shunted by a diode D1 which is rendered conductive by the amplified synchronizing signals and generates a negative voltage which is applied to the grid of the valve VI for automatically adjusting its working point and completely suppressing the intelligence signals. This biassing voltage is derived from the resistance R4 and shunt condenser C4 in the anode circuit of the diode which is charged negatively when the diode is conducting, and is applied to the grid of the valve VI through the circuit comprising resistances R5, R1 and the decoupling condenser C5. A fixed bias is applied to the' grid of the valve V1 by the resistance R7 and shunt condenser C6.
